Provide a way for block authors to allow content into the excerpt from a columns type block.

[britner]

Hey!

I would like a way for block authors to allow their nested blocks to be used to render the excerpt. I know that you can allow specific blocks to be rendered but if the block structure is similar to core columns blocks the content is ignored. This is because core columns have specific code in place to allow their content to be used. I don't understand why it's set up this way for only core columns to get their inner blocks checked.

I also don't understand why only core blocks are allowed inside inner content? There is no filter for the $allowed_inner_blocks variable.

If this is something I can help with I would be happy to submit a pull request.

Thanks for the ticket @britner!

The code that generates excerpts needs to be enhanced to cover more types of group blocks. This was first noted in #46133 and is now tracked in #47637.

I've marked this as a duplicate of #47637.
